The files you added are not going to be available on the docs as is, you'll need to link to them somewhere, for example in the index.rst

The first headline in each file determines what the link to it will display, also having the same value for that in multiple files leads to only one being chosen to be displayed, so you might want to change those to something like Minecraft Dependencies etc
